We were a family of 6, including a 2 year old and 7 month old. After much research, we decided to rent one of the 6 seater golf carts from Sunshine Scooters (which included 2 car seats). It is only a couple of blocks from the port for pick up. The rules are basically the same as driving a car...seat belts; car seats; pay for parking; etc. We just took our time driving around and seeing the sites and the beach. Then we planned on taking our little ones the Truman Splash Park along the water. There is lots of pay parking there - a lovely, large, green space where we all could "cool off" a bit. More shaded seating would be a good idea there, but many of us just sat on our towels on the grass. A picnic lunch was ideal. We could even see our cruise ship docked closeby. It was a good few hours on our own in port.
